It is very necessary on air safety risk quantitative analysis research. Especially in China, radar control is being gradually implemented, in order to ensure air traffic safety, the study of quantitative analysis and evaluation of radar control on security risks has become gTeat significance and practical value. This paper studies the safety assessment method of aircraft radar separation in the case of air traffic flow increasing. Based on the close approach probability (CAP) model and the reference system comparison method, consider the various factors that affect flight safety, the radar separation evaluation model is established. Using statistical knowledge and measured data, the method of this study is verified by compare, the result is displayed in the premise of ensuring flight safety, radar type is related with radar safety separation. Reduced radar separation can greatly improve air traffic flow, ease flight delays, enhance control efficiency. 收起
